Optical drives never require a driver when used in any Windows os from Win95 up. Windows XP provides native support that allows this drive to read a data or music disk and to burn a cd-r disk. No support for playing dvd disks or for burning dvd or cd-rw disks. For those tasks, compatible recording & dvd decoding software is required.
